  Enhanced features such as sophisticated ratio control, oxygen (O2) enrichment, improved burner design, etc., facilitate more operating flexibility of Claus units to rapidly adjust to changing feed conditions. Varying feedrates are normal operating conditions in petroleum refineries and natural gas processing facilities. However, even with these mentioned advancements, some process applications still challenge the capability of adjusting Claus units to large turndown ratios while maintaining high sulfur removal and onstream efficiencies. New processing methods incorporate a liquid redox process with a Claus unit. Such combinations can achieve turndown ratios of 100%, removal effici
